MTH BLUE COMET

OPERATING INSTRUCTIONS

Thank you for purchasing the MTH Electric Trains die-cast Blue Comet
steam locomotive. This ¼" scale reproduction of the famous Blue Comet
locomotive measures over 22" in length and weighs over 9 pounds. Despite
its scale size, the locomotive is capable of operating on O-42 3-rail track
with any compatible AC transformer, (see page 34 for a complete list of
compatible transformers and wiring instructions) and is completely
compatible with most other 3-rail locomotives, rolling stock and
accessories.
The locomotive and tender are equipped with several deluxe features that
are simple and fun to operate. Each feature is described among the
following pages which should be read before the engine is operated. For
those of you who can't wait to get started, the Quick Start Operating
Instructions, found on page 3, should be read so that you understand the
basics of the operating system. Those features marked for 2 and 3-rail
engines are available in both types of engines. Features not marked as such
are only available in the 3-rail version.
